Product Description:
The 8V1016.501-2 is a single-axis servo inverter manufactured by B&R Automation within the 8V1 ACOPOS Servo Drives series. It measures only 58.5 mm in width, 220 mm in depth, and 257 mm in height while weighing 2.5 kg, so it fits in densely populated control cabinets. The drive conditions DC bus energy and delivers regulated three-phase power to synchronous or induction motors used in pick-and-place stations, packaging lines, and material-handling cells. Its compact enclosure allows several coordinated axes to be installed in the same cabinet without consuming excessive panel space.
The power stage provides a continuous phase current of 3.6 A RMS, allowing it to supply up to 0.7 kW of mechanical shaft power when paired with a compatible motor. For rapid acceleration, it supports a peak current of 12 A RMS, and the IGBTs operate at a nominal switching frequency of 10 kHz to reduce torque ripple. The inverter can modulate motor voltage at frequencies up to 598 Hz, keeping high-speed spindles and servo axes within the vector-control range. The maximum connected load is 2.1 kVA, which helps determine appropriate cabinet fuses and conductor sizes. Three plug-in option slots accept encoder or fieldbus modules, providing flexibility for different feedback and communication arrangements. Motor cables may extend up to 15 m without exceeding the permitted voltage drop, allowing the inverter to be installed away from the driven axis when cabinet placement requires additional routing distance.
During regeneration, the integrated chopper routes surplus kinetic energy to an external resistor, preventing excessive DC bus voltage as the motor decelerates. It can dissipate 130 W continuously and withstand bursts of 1.9 kW, while the brake transistor can switch up to 1.3 A of DC-link current during each deceleration. A bulk capacitance of 2040 µF stabilizes the 540 V DC bus so voltage excursions remain within safe semiconductor limits. This arrangement allows returned energy to be handled outside the inverter while the internal switching device regulates current through the connected resistor. Proper resistor selection must account for both the continuous dissipation rate and the short-duration braking load encountered during repeated motion cycles.
